argenx combines the diversity of the llama immune system with antibody engineering advancing a clinical pipeline to treat patients with cancer and severe autoimmune diseases. The argenx platform allows to unlock novel and complex targets and develop antibody-based drugs designed for greater efficacy and longer duration of effect.

Human antibodies for novel targets and underserved diseases

argenx develops product candidates with the potential to be either first-in-class against novel targets or best-in-class against known, but complex, targets in order to treat diseases with a significant unmet medical need. This is enabled by our suite of differentiated technologies. The SIMPLE Antibody™ Platform, based on the powerful llama immune system, allows argenx to exploit novel and complex targets, and our three antibody engineering technologies are designed to enable us to expand the therapeutic index of our product candidates.
